This invention relates to an edge binding for sheet material and to amethod of making and applying the binding to finish the edges of sheetmaterial and although capable of general use is more particularlydesigned for use in the shoe manufacturing industry.

In the manufacture of shoes, it has heretofore been customary to finishthe edges of certain parts of the shoes, such as uppers, Vamps,

straps, and similar parts, with what has been commonly called Frenchcord binding. Thls is accomplished by placing the binding flat on theright face of the shoe part and then stitching the two together by a rowof stitching close to their edges. The binding is then turned in areverse direction around the edge of the shoe part concealing thestitching and the free edge of the binding is cemented to the wrong sideof the shoe part. The reverse 2 turning of the binding over its stitchededge and around the edge of the shoe part presents an appearance fromthe right side of the shoe part of a cord binding, hence the name. Inmany cases, it has been customary to reenforce the shoe part on itswrong side and adjacent its edge with a strip or stay of suitablereenforcing material and generally this is done before the binding isturned over upon the wrong side of the shoe part so that the bindingwill ultimately cover the reenforcing strip. It may, however, be done inthe reverse order. The application of the lining to the shoe partconceals the turned over edge of the binding and the stay. This work,however, involves a number of separate operations performed by diflerentoperators and necessitates the passing of the shoe from one to the otherthrough a number of steps, all of which consume time and labor andinvolve expense.

The principal object of our invention is the provision of a bindingwhich is adapted to stay or reenforce the edge of the shoe part to whichit is. applied and to this end the 46 binding includes a reenforcingstrip secured to one face thereof in any suitable manner, thereenforcing strip being of a lesser width than the binding so that whenthe binding is applied the reenforcing strip is properly po- 5 sitionedon the shoe part.

Another object of the invention is the rovision of a binding made instrip form w ich can be manufactured at a low cost.

A further object is the provision of a method for binding the edge ofsheet material which will eliminate some of the steps now required,which will obtain a better result and better finished edges and whichgreatly reduces the expense of the binding operation and permits thework to go through more rapidly.

Other objects of the invention will be more specifically set forth anddescribed hereinafter.

Referring tothe drawings illustrating our invention, Figure 1 is asectional View of a shoe part in sheet form having attached to one edgethereof by stitching a binding constructed in accordance with ourinvention, the binding being shown after it has been stitched to theshoe part and before it has been turned around the edge; Fig. 2 is asimilar view of a binding turned in a reverse direction around the edgeof the shoe part and secured to the wrong face of the shoe part; Fig. 3is a cross-sectional view of a binding strip constructed in accordancewith our invention and Fig. 4 is a view in perspective of a portion of ashoe upper provided with an elongated strap, said shoe part being shownas bound with a binding made in accordance with our invention, one endof the binding strip being opened up to illustrate its application tothe shoe part.

Referring to the drawings, 10 designates a binding strip of any suitablematerial which is preferably provided with at least one selvaged edge 12to prevent the stitches pulling out when it is stitched at that edge toa shoe art. The other edge 14 may or may not e selvaged as desired. Toone face of the binding strip is secured a strip 16 of suitablereenforcing material of lesser width than the width of the bindingstrip, the reenforc ing strip being positioned adjacent the un selvagededge of the-binding. The reenforcing strip 16 may be secured to thebinding, strip by cement or other adhesive (as shown in Fig. 3) or bystitching or by ang other means or it may be formed in the inding 100 inthe weaving process as an integral part thereof. The binding is made ina continuous form as a tape orribbon rolled or wound on a board and iscut off in suitable lengths for use.

Preferably, the reenforced portion of the binding is of such width inrelation to the width of the binding that when the binding is used, thereenforced portion lies entirely.

with its selvaged edge 12 in register with the edge 22 of the shoe partand secured thereto by a row of stitching 24 adjacentthe edfges er asshown in Figure 1. The binding a ing it around.v the edge being stitchedis then turned in a reverse direction around the edge of the shoe partto be bound and its free edge 14 is preferably cemented to thewrong sideof the shoe part as shown in Fig. 2. In positioning the binding inrelation to the shoe part preparatory to stitching it thereto, it may beso placed that the reenforcing tape will lie finally as shown in Fig. 2between the free edge of the binding and the wrong face of-the shoe orwill lieoutside of the bindin with the latter between the former and t ereenforcing strip.

Certain stepsof our method such as stitching the binding to the shoepart and turnto be-bound may be carried out by the use of suitablesewing and folding machines respectively or the entire metliiodmay becarried out by hand if desire method the various steps now required inbinding the edges of shoe parts have been reduced to a minimum andcertain steps involving movement of shoe parts back and I forth from oneoperator to another have been eliminated, thereby effecting an economyof manufacture and facilitating the progress of the work through thefactory. In addition the work is improved in character for the reasonthat when the reenforcing stri or stay is made an integral part of thebin ing, it is accurately located in relation to the edge to bereenforced thereby bringing about work which is uniform, accuratelyreenforced and-neat. Our method further eliminates the cementing processrequired 'when the reenforced strip or Sta-y is cemented to the shoepartindependently of the application of the binding, which, of course,is a desired advantag'e because any reduction in cementing in "a shoefactory is of marked benefit; This is especially emphasized in'bindingshoe parts It will be observed that by the use of our strip,

forms of binding where it is desirable to have V the edge reenforced.

What we claim is:

1. A wovenbinding strip for binding the edge of sheet material havingsecured to one face a strip of tape reenforcing material of lesser widththan the width of said binding strip 2. woven binding strip for bindingthe edge of sheet material, having secured to onev face thereof a stripof reenforcing material of lesser width than the width of said bindingstrip, one edge of said reenforcing strip being substantially inregister with one edge of said binding strip.

3. An elongated woven binding strip for binding the edge of sheetmaterial, provided with a selvaged edge and having a strip ofreenforcing material secured toone face thereof with one edge inregister with one edge of said binding strip, said reenforcing stripbeing in width approximately one half 0 the width of said binding strip.

4. A woven binding strip selvaged on one edge for binding the edge ofsheet material and having cemented to one face thereof a strip ofreenforcing tape of lesser width than the width of said binding strip;one edge of said tape being in register with the selvaged edge of saidbinding strip.

5. The herein described method of binding sheet material consisting inproviding an elongated binding strip having one edge selvaged, cementingto one face of said binding strip a strip of reenforcing tape with itsedge adjacent with the unselvaged edge of sa1d binding strip, saidreenforcing str1p bein of lesser width than the width of said bin ingstrip, then stitching said binding strip along its selvaged edge to theright face of the sheet material to be bound at the edgethereof, thenturning said binding in reverse direction around the edge of said sheetmaterial and securing said reenforced portion of said binding tothe'reverse side of said sheet material.

6. The herein described method of simultaneously binding and reinforcingthe edge of sheet material consisting in securing to one face of a wovenbinding strip adjacent one edge thereof a strip of reinforcing tape oflesser width-than the width of said binding then stitching said binding'strip along its unreinforced edge to the right face of the sheetmaterial to be bound at the edge thereof, then turning said binding in areverse direction around the edge of said sheet material and securingthe reinforced portion of said
